The 510(k) summary describes a mechanical implant (femoral stem) and its modifications. There is no mention of AI, ML, image processing, or any software-driven functionality that would suggest the use of these technologies. The performance studies focus on mechanical fatigue testing.
Yes
The device is a prosthetic replacement for the proximal portion of the femur, used in total hip replacement to treat degenerative joint diseases and failed surgeries. These applications clearly indicate its role in alleviating conditions and restoring function, classifying it as a therapeutic device.
No
This device is a prosthetic femoral stem used in total hip replacement, which is a treatment for joint diseases, not a tool for diagnosing them.
No
The device description clearly states it is a "Femoral Stem," which is a physical implant used in hip replacement surgery, not a software-only device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The CLS™ Spotorno™ Femoral Stem is a prosthetic implant intended for surgical replacement of a portion of the femur. It is a physical device implanted into the body, not a test performed on a sample outside the body.
- Intended Use: The intended use describes the treatment of joint diseases and failed surgeries through surgical implantation, not diagnostic testing.
The information provided clearly describes a surgical implant, which falls under the category of medical devices, but not specifically in vitro diagnostics.

Intended Use / Indications for Use
The CLS™ Spotorno™ Femoral Stem is intended for use as a prosthetic replacement of the proximal portion of the femur during total hip arthroplasty. It is indicated for cementless use in total hip replacement in treatment of the following: patient conditions of noninflammatory degenerative joint disease (NIDJD), e.g. avascular necrosis, osteoarthritis and conditions of inflammatory degenerative joint disease (IJD), e.g. rheumatoid arthritis; those patients with failed previous surgery where pain, deformity, or dysfunction persists; revision of previously failed hip arthroplasty.

This Special 510(k) incorporates the following changes as compared to the original device configuration: 1) addition of the CLS 125° stem, with an increased offset; and 2) incorporation of a slim neck and short taper. Below the resection line, the design of the modified stem remains the same as the legally marketed device.

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
Classification. Class II.

This Special 510(k) incorporates the following changes as compared to the original device configuration: 1) addition of the CLS 125° stem, with an increased offset; and 2) incorporation of a slim neck and short taper. Below the resection line, the design of the modified stem remains the same as the legally marketed device.
Substantial Equivalence:
The modified CLS™ Spotorno™ Stem is substantially equivalent in terms of fundamental design, materials, manufacturing, indications for use and intended use to the previously cleared, currently marketed CLS™ Stems.
Verification activities included fatigue testing of the CLS 125° to ensure that the modified design is safe and effective. All test samples met the acceptance criteria, thus indicating that the device, as modified, will survive physiological loading.
